VAPOR-STOVE AND HEATING APPARATUS.

51 E CIPIC'ATXON forming part of Letters Patent No. 364-,510, dated June 7. 1857.

Application fllcd September 18, 1886. Serial No. 3l3,9l5. (No model.)

To all whom it may concern:

Be it known that I, XENOIHON HANNA, a' citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements inVaporStoves and Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact descrip tion ot'theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention is an improvement in vapor stoves and heaters in which gasoline, coal-oil, and other products of petroleum are vaporized by means of hot water and steam, which steam in turn is produced by the burning vapor for that purpose, and also for the purpose of heating or cooking until the supply of the fluid in the generator is exhausted.

Heretofore to ignite vapor-stoves the bran ers usually have been constructed so that a portion of the fluid had to be drawn into cups under the burner and ignited to supply the required heat to the pipes to begin the vaporr zation before lighting the burner. This burning fluid, especially in gasoline-stoves, produces a disagreeable odor and smoke. Airpressure has also been resorted to for the same purpose, both of which have been dispensed with in my device. By means of heat, hot water, or steam I am enabled in my device to obtain a more uniform flow of vapor or gas. The generator being incased in water or steam, the fluid never comes into direct contact with the flame, and can be placed at any required distance from it. Consequently there is absolutely no danger from explosions.

The objects of my invention are, first, 'to so cure a nox explosive gasol'inestove; second, to secure a portable safe vapor-heater, and, third, a combination of both, which, besides being a cheap, useful, and economical piece of furniture for the home, will be also a hand some ornament. I attain these'objects by the mechanism shown by the accompanying drawings, in which- Figure I is a vertical section of the combined generator, heater, and stove.

Fig. II is a vertical section of aportable heater, the generator being arranged in a modified form.

Similar letters refer to similar parts in both views.

The letter A represents a tight metal reservoir of any desired shape, having pipe H, provided with stop-cock 1.

B represents a similarly-shaped reservoir to A, but smaller and placed within reservoirA, and having pipe D, provided with stop-cock 2 and passing through the shell of reservoir A. Into the space between reservoirs A and B, and through pipe H, hot water is poured, and pipe H closed by stopcock 1. Through pipe D gasoline or other fluid to be vaporized is poured into reservoir 13, and pipe D closed by stop-cock 2.

E E represent a number of ordinary steampipes with curved tops, inserted at their lower ends into the top covering of hot-water box F. These pipes are connected with reservoir A,above water-line h h, by steam-pipe a, provided with stop-cock g, and below water-line h h, and entering hot-water box F near the bot tom, by hot-water pipe a, provided with stopcock g.

G is an ordinary gas-pipe, provided with valve 0, piercing the shell of reservoir A, and entering reservoir B near its top, and conveying the vapor from reservoir B to burners c c 0' between pipes E E.

O is a similar gas-pipe, provided with valve '6, leading down from pipe G and under hotwater box F, conveying 111 c vapor to burners c c c.

c c. c and c c o are the ordinary needlepointed gasoline-burners,provided with valves to regulate the flow of vapor and the size of the flame, and are attached to vapor-pipes G and O.

F is a metallic waterbox of any desired shape, havinga heatingsurface 011 its under side. It also serves as a support for the framework of the heater and stovetop J.

G is an ordinary steam-gage for registering the steam-pressure in pipes E E.

J is the stove-top, also serving for top of frame-work of the heater.

K K K are stove-holes, which maybe provived with gratings, upon which rest the cooking utensils. 1

k is the discharge-pipe, provided with astopcock, by means of which the water in the heater can all be drawn off when necessary.

The action of my deviceis as follows: Reservoir B is filled about two-thirds with gasoline or other fluid which is to be vaporized. Hot water is nowpoured into reservoir A,and, passing through the water-box F, rises to the same level in the radiating pipes E E as in reservoir A, which generates sufficient vapor to light. the burners cc 0, the heat from which on water-box F immediately furnishes more hot water and steam, and which in turn vaporizes more fluid, and so on until the fluid in reservoir B is exhausted. After starting, by means ofstop-cocks gand g,0n]y a sufficient amount of steam or hot water enters reservoir A from the heater to produce vaporization, and the surplus is retained in the heater for heating or cooking purposes. By means of valves 0 and e the flow of vapor to the burners ccc and 00 0, respectively, is controlled and made uniform, as near as possible, or shut off.

I do not propose to limitmyself in the exact construction of these several parts, for in Fig. II the arrangement of parts of my heater is modified. A is a metal water-box of any desired shape,'with heatingsurface beneath and connected with a similarlyshap'ed steamtight chest, A, which forms the top of the heater, by frame-work and steam-pipesE E. B represents a similarly-shaped reservoir to water-box A,butsmaller,suspended and incased within it, provided with pipe andstop-cock D. Orepresents a vapor-pipe to conduct the vapor from reservoir B, passing through the shell of reservoir A, to burners c c c beneath waterboX A, and provided with valve 0, to control the flow of vapor. E E are ordinary steampipes inserted at their lower ends into the top covering of waterbox A and connecting it with steanrch est A. G is an ordinary steam gage to register thesteam-pressure in the heater. H is a pipe inserted into water'box A, provided with a stopcock. k is the discharge-pipe, provided with a stopcock, by means of which the water in the heater can all be drawn off when necessary. 0 c c are the ordinary needle gasoline-burners, provided with valves to regulate the flow of vapor and the size of the flame.

The action of my device in its modified form, as shown in Fig. II, is very similar to that as shown in Fig. I. Reservoir B is partly filled with the fluid to be vaporized. and stop-cock in D is closed. with hot water through 11 and stop cock closed. The action of the hot water produces vapor in reservoir B, which passes through pipe 0 to burners c o c, which are lighted, the heat from which on water-box A immediately furnishes more hot waterand then steam for pipes E E, and which in turn vaporizes more fluid, and so on until the fluid in reservoir B is exhausted.

Thus in one way, as in Fig. I, we have a complete steam-heater and stove, and in the other, as in Fig. II, aeomplete portable steamheater, either of which is especially adapted for coal-oil, which requires a greater degree of heat to vaporize than do other products of pctrolenm.

Having sufficientlydescribed my invention,

what I claim, and desire to secure by Letters Patent, is-

1. The combination, with a radiator, substantially as shown, of a gasoline-tank, a hot water supply surrounding said tank, substantially as described, and connecting with the radiatorfor generating the preliminary supply of vapor, and a vapor-pipe provided with burners under the radiator, for increasing the heat of the water to augment the generation of vapor, as set forth.

2. The combination, with the heater provided with the bent pipes, the hot-water tank, and a stove-top, of the gasoline-tank, the sur rounding hot-water tank, the valved circulating-pipes between the heater and the tank about the gasoline-receptacle, and the valved vaporpipes provided with burners under the hot-water tank of the heater and the stove-top, respectively, as set forth.
